Question of the Day

Estimated Rows

I have two calls to the GENERATE_SERIES TVF in this code:

SELECT   TOP 10 gs.value
FROM     GENERATE_SERIES(1, 10) AS gs
ORDER BY NEWID ()
OPTION (RECOMPILE);
go
DECLARE @a int = 10;
SELECT   TOP (@a) gs.value
FROM     GENERATE_SERIES(1, @a) AS gs
ORDER BY NEWID ()
OPTION (RECOMPILE);
In the actual query plans, what is the estimated number of rows for each batch in SQL Server 2022?
